Creating EJB Module Projects 
Use
Before you can create an enterprise bean, you need an EJB Module project to which you can assign it. The EJB Module project also contains the deployment descriptors that will be included in the EJB JAR file. The EJB Module Project can be referenced from an Enterprise Application project for deployment.
